prolog_skip_level(-Old, +New)

Unify Old with the old value of‘skip level’and then set this level according to New. New is an integer, the atom very_deep (meaning don't skip) or the atom skip_in_redo (see prolog_skip_frame/1). The‘skip level’is a setting of each Prolog thread that disables the debugger on all recursion levels deeper than the level of the variable. See also prolog_skip_frame/1.
